WELL-DRILLING MACHINE.

Specification of Letters Patent.

Patented Dec. 31, 1912.

Application led March 4, 1912. Serial No. 681,527.

To all whom t may concern Y Be it known that I, RAY C. FAGAN, a citizen of the United States, and. resident of Spangler, Cambria county, State of Pennsylvania, have invented certain new and useful Improvements in .lVell-Drilling Machines, and my preferred manner of carrying out the invention is set forth in the following full, clear, and exact description, terminating with claims particularly specifying the novelty.

This invention is a portable we ll drilling machine, and the objects of the same are to improve the general construction of machines of this character,-to mount the whole on a small truck so it will be light and easily moved 'by team or by its own or other trac' tion power, to dispose the parts within small compass 'and place the controls within easyreach, of a single operator, and have the mast. foldable for purposes of transportation.

IEspecially Vthe novel features of this invention are the construction of the beam and the means for rocking it, the vacuum cushion for its strokes and the manner of mounting and adjusting'said cushion, thedevices for handling the several drilling tools, and other details which will appear in lthe following specification and claims and which are shown in the accompanying drawings, wherein- Figure 1 is a general side elevation of this machine complete.V Fig. 2 is a central vertical longitudinal section of the lower portion, and Fig. 3 a front end elevation thereof. Fig. 4 is a horizontal section taken on the line 4 4 of Fig. 1, and Figw is a horizontal section substantially on line 5--5` type, mainly because one man can attend it,

no water is needed and no fuel but the gasolene7 it is serviceable where water is scarce or in temperatureswhen Vwater would freeze,

and the power developed is large in proporv tion to the space occupied by the engine. 0n the driving' or fly-Wheel shaft 5 is slidably mounted a friction-Wheel 6 adapted` to make contact alternately with friction disks 7 and 8 which are fast ony al cross shaft 9 slldable 1n its bearings and carrying a wide gear pinion 10; and the speed is increased or decreased by moving the wheel 6 toward or from the shaft 9, while its direction is cated to a gear 11 whose shaft carries -a bevel gear 12 meshing with another bevel gear 13 splined as at 14 on the main shaft 15 which extends along above one side bar of the frame of the truck 3 and rotates and slides ,in its bearings 16. This shaft preferably carries a grooved collar 17 engaged by a fork 18 at one end of a slide 19 whose handle 20 is within convenient reach of the .operator when he stands near the well, and from it are driven the several instrumentalil ties described below. 0r, one operator could control theengine and another could control the work to be .performed thereby.

The .superstructure comprises a number of uprights 21 supporting a top frame 22, a derrick 23 pivoted at 24 thereon and suitably braced as at 25,i and a crown wheel 26 and a second wheel 26 j ournaled inthe top of.I the derrick. The numeral 27 designates soy a Walking beam having a. shaft 28 fast through it between its ends, the shaft being mounted in journals 29,0n a. cross bar of the frame 22, and the rear end of the beam" is forked as at 30 and carries a cross pin 31 Y on which is'journaled a sheave 32. The beam is rocked by ak connecting rod 36 whose upper end is forked as at 37 and the arms thereof pivoted on the extremitiesof said `pin 3l astride the fork 30,; while the lower .end of the rod 36 is pivoted on a crank pin 40 projecting from a gear 41 journaled in bearings onthe truck 3. This gear ismrevolved by a pinion 42 which is fast on a cross shaft- 43 having a bevel gear 44, and one `end-of the main shaft 15 carries a bevel gear: 4 5.which may be thrown into mesh vBvith the bevel gear 44 at will, as seen in 1g. 4. For hauling up. the tools the main shaft has; another bevel gear 46 adapted to bel thrown into mesh with a bevel gear t7 on the shaft of a windlass i8 journaled in the truck, and the rope 49 from the windlass leads over a sheave 50 on the main frame, thence forward and under the slieave 82 on the beam, thence upward over the crown wheel Q6, and thence downward to the tool in a manner well known. For drilling with the taper screw, the rope 49 will be led direct from the windlass over the crown wheel as shown in dotted lines `in Fig. l. The direction of rotation ofthe windlass, and therefore whether it pays out or winds up the rope is controlled by reversing the direction of rotation of the main shaftI 15 in the manner described above,'the speed is similarly controlled, and a brake shoe 52 may be applied and used if needed. But the power shaft cannot rotate the drum and rock the beam simultaneously, as .will-be clear from Fig. 4. l

lhe cushion for the beam comprises a 'cylinder 53 open at its lower end, a piston 54C therein, and a piston rod 55 whose lower extremity is mounted on a iiXed pivot, such as the shaft 56 of the gear 41. Projecting rigidly from the walking beam shaft 28 vand standing alongside the rear portion of said beam is an arm 57 provided with a series of holes 58,into any one of which may be inserted a pin 59 whereby an eye 53 at the upper end of the cylindery 53 is connected with the arm and the cylinder caused to rise and fall therewith as the arm moves during the rocking of the beam. The vac. uum created as the rear end of the walking beam rises tends to oppose the weight Yof the tool, and therefore assists the engine. 'lhis detail of construction l consider important, not only because of its usefulness as described, but also because it adds but litle weight to the machine withpractically no complicztion of parts, means are present for adjusting the throw of the piston, and it is impossible for a vacuum cushion to freeze.

For hailing out the well, the sand line 60 is led upward from the well,'over the wheel 26 in the derrick, and down to a small windlass orfdrum 60 fast on a shaft 61 mounted at one end in a fixed journal 2v and 'at the other en d in a box 63 standing above the main shaft 15 and carried :by a lever 6a pivoted at one end at 65 in the frame. lts yother end is connected by a link 66 with a lever 67 which leads forward andv has a. handle 68 convenient to the operator standing nearthe well, who may thereby raise and lower the box at will. Near the latter the shaft 61 carries a friction wheel 70 adapted when depressedto make contact with a wide frittion wheel 71 on the main shaft or when raised to make contact with a brake shoe I2-carried by the frame. Thus the operator, by properly moving the handle 68, may cause the rotation of the drum 60 employ noaaoee to wind up the sand line, or may check its rotation and hold the drum against rota tion, or may free the drum entirely to per mit the bailer to descend into the well.

rlhe temper screw support is perhaps best illustrated in Fig. 2. This consists of an l shaped member YB whose shank lies on the front end of the beam Q7 and is hinged at its extremity thereon as at 74, while its foot hangs'vertically over the frontend of the beam and has its outer edge grooved as at T5 on the 'arc of a circle struck around the pivot 28. in this groove lies a wire 'rope 76 whose lower end is connected with the temper screw T, while its upper end is carried over onto the shank of the member 73 and fastened thereto as at 77; therefore when the beam is rocked o n its pivot, the temper screw is caused to move through a strictly vertical path as will be seen from ltig. 2, but use the entire member can be turned over its hinge out of the way of the main line leading downward from the crown' wheel as shown in dotted lines in Fig. 1. By the employment of this ,detail in a well rig, a heavy tool may be instantly and conveniently shifted without. moving'the machine or interrupting the position of its various parts. While l prefer to use a gasolene engine for the reasons above given, l might steam, electricity, or water power, or belt the power from any suitable source to the shaft 5.
